43-215 - Standardized Procedures for Performing Aircraft Magnetic Compass Calibration

Date Issued
August 07, 2017
Responsible Office
AFS-300
Description
This advisory circular (AC) describes procedures for calibrating an aircraft magnetic compass to minimize the effect of aircraft-induced magnetic fields. These procedures are often referred to as “swinging the compass” or a “compass swing.” This AC is not mandatory and does not constitute a regulation. These means are not the only means to perform aircraft compass calibration. However, if you use one of the means described in this AC, you must follow it in all important respects. The content of this AC may be of interest to aircraft technicians performing compass swings or to users of aircraft compass systems.
